1. Take off the cover.
2. Install the base. In case of wall mounting, ix the base to the wall with 2 screws
Ø 4 mm and corresponding dowels according to the quality of the wall. In case
of installation on a mounting bracket, use a bracket TS 35/7.5.
3. Make the electric connection.
4. Install the cover.

5.2 Parametrization
The control direction is set with jumper 1:
NO operation: Jumper 1 = ON
NC operation: Jumper 1 = OFF
The ixed follow-up time of 2 minutes of the pump or the
boiler can be increased by further 5, 10 or 15 minutes
using jumper 2 and 3:

6 Electric connection
For the connection of the voltage supply, the cable sections must be a minimum of 0.75 mm² for 24 V or 1.5 mm² for 230 V. The voltage supply of the 24 V version must
come from a safety transformer according to EN 61558-2-6 or, for North America, from a Class II Transformer according to UL. Depending on the voltage version of the
base, it is possible to take L1 or L and L2 or N, as well as the protective conductor, from the base. If no temperature limiter is connected, the connection TB/%H must be
bridged (provided for at the factory). The bridge must be removed as soon as a temperature limiter is connected. The temperature limiter must be a normally closed contact.
The wiring of the thermostats depends on the present ba-
sis. For wiring purposes, please observe the instructions of
the thermostat or of the respective component.

9 Dismantling
WARNING!Electrical voltage! Danger to life!
• Always disconnect the base from the mains network and secure against
unintended activation before opening.
• Disconnect external voltages and secure against unintended activation.
• De-energise the complete installation.
• Remove the wiring to all externally connected components.
• Remove the base and dispose it of properly, if necessary.
